Abstract

Система и способ введения материала, например, в виде пены в разнесенные полости или участки в сигаретном фильтре или в фильтрующем стержне. Имеется лента, приспособленная для синхронного движения вместе с движущимся сигаретным фильтром или фильтрующим стержнем. Из ленты выступает множество инжекционных игл, расположенных с интервалами, совпадающими с интервалами между разнесенными полостями в сигаретном фильтре или фильтрующем стержне. Камера, содержащая материал в виде расширяющейся пены, сообщена по текучей среде с одной или более из инжекционных игл в одном или более мест по пути движения инжекционных игл.The system and method of introducing the material, for example, in the form of foam in spaced cavities or areas in a cigarette filter or filter rod. There is a tape adapted for synchronous movement with a moving cigarette filter or filter rod. A plurality of injection needles protrude from the tape at intervals that coincide with the intervals between the spaced cavities in the cigarette filter or filter rod. A chamber containing material in the form of an expanding foam is in fluid communication with one or more of the injection needles at one or more locations along the path of the injection needles.
